++ trunk/HISTORY (local) $Id: HISTORY,v 1.1325 2006/08/15 15:38:37 debug Exp $ 20060723 More Transputer instructions (pfix, nfix, opr, mint, ldl, ldlp, eqc, rev, ajw, stl, stlf, sthf, sub, ldnl, ldnlp, ldpi, move, wcnt, add, bcnt). Adding more SPARC instructions (andcc, addcc, bl, rdpr). Progress on the igsfb framebuffer used by NetBSD/netwinder. Enabling 8-bit fills in dev_fb. NetBSD/netwinder 3.0.1 can now run from a disk image :-) 20060724 Cleanup/performance fix for 64-bit virtual translation table updates (by removing the "timestamp" stuff). A full NetBSD/pmax 3.0.1 install for R4400 has dropped from 667 seconds to 584 :) Fixing the igsfb "almost vga" color (it is 24-bit, not 18-bit). Adding some MIPS instruction combinations (3*lw, and 3*addu). The 8048 keyboard now turns off interrupt enable between the KBR_ACK and the KBR_RSTDONE, to work better with Linux 2.6. Not causing PPC DEC interrupts if PPC_NO_DEC is set for a specific CPU; NetBSD/bebox gets slightly further than before. Adding some more SPARC instructions: branches, udiv. 20060725 Refreshing dev_pckbc.c a little. Cleanups for the SH emulation mode, and adding the first "compact" (16-bit) instructions: various simple movs, nop, shll, stc, or, ldc. 20060726 Adding dummy "pcn" (AMD PCnet NIC) PCI glue. 20060727 Various cleanups; removing stuff from cpu.h, such as running_translated (not really meaningful anymore), and page flags (breaking into the debugger clears all translations anyway). Minor MIPS instruction combination updates. 20060807 Expanding the 3*sw and 3*lw MIPS instruction combinations to work with 2* and 4* too, resulting in a minor performance gain. Implementing a usleep hack for the RM52xx/MIPS32/MIPS64 "wait" instruction (when emulating 1 cpu). 20060808 Experimenting with some more MIPS instruction combinations. Implementing support for showing a (hardcoded 12x22) text cursor in igsfb. 20060809 Simplifying the NetBSD/evbmips (Malta) install instructions somewhat (by using a NetBSD/pmax ramdisk install kernel). 20060812 Experimenting more with the MIPS 'wait' instruction. PCI configuration register writes can now be handled, which allow PCI IDE controllers to work with NetBSD/Malta 3.0.1 and NetBSD/cobalt 3.0.1. (Previously only NetBSD 2.1 worked.) 20060813 Updating dev_gt.c based on numbers from Alec Voropay, to enable Linux 2.6 to use PCI on Malta. Continuing on Algor interrupt stuff. 20060814 Adding support for routing ISA interrupts to two different interrupts, making it possible to run NetBSD/algor :-) 20060814-15 Testing for the release. ============== RELEASE 0.4.2 ==============
++ trunk/HISTORY (local) $Id: HISTORY,v 1.707 2005/04/27 16:37:33 debug Exp $ 20050408 Some minor updates to the wdc. Linux now doesn't complain anymore if a disk is non-present. 20050409 Various minor fixes (a bintrans bug, and some other things). The wdc seems to work with Playstation2 emulation, but there is a _long_ annoying delay when disks are detected. Fixing a really important bintrans bug (when devices and RAM are mixed within 4KB pages), which was triggered with NetBSD/playstation2 kernels. 20050410 Adding a dummy dev_ps2_ether (just so that NetBSD doesn't complain as much during bootup). Symbols starting with '$' are now ignored. Renaming dev_ps2_ohci.c to dev_ohci.c, etc. 20050411 Moving the bintrans-cache-isolation check from cpu_mips.c to cpu_mips_coproc.c. (I thought this would give a speedup, but it's not noticable.) Better playstation2 sbus interrupt code. Skip ahead many ticks if the count register is read manually. (This increases the speed of delay-loops that simply read the count register.) 20050412 Updates to the playstation2 timer/interrupt code. Some other minor updates. 20050413 NetBSD/cobalt runs from a disk image :-) including userland; updating the documentation on how to install NetBSD/cobalt using NetBSD/pmax (!). Some minor bintrans updates (no real speed improvement) and other minor updates (playstation2 now uses the -o options). 20050414 Adding a dummy x86 (and AMD64) mode. 20050415 Adding some (32-bit and 16-bit) x86 instructions. Adding some initial support for non-SCSI, non-IDE floppy images. (The x86 mode can boot from these, more or less.) Moving the devices/ and include/ directories to src/devices/ and src/include/, respectively. 20050416 Continuing on the x86 stuff. (Adding pc_bios.c and some simple support for software interrupts in 16-bit mode.) 20050417 Ripping out most of the x86 instruction decoding stuff, trying to rewrite it in a cleaner way. Disabling some of the least working CPU families in the configure script (sparc, x86, alpha, hppa), so that they are not enabled by default. 20050418 Trying to fix the bug which caused problems when turning on and off bintrans interactively, by flushing the bintrans cache whenever bintrans is manually (re)enabled. 20050419 Adding the 'lswi' ppc instruction. Minor updates to the x86 instruction decoding. 20050420 Renaming x86 register name indices from R_xx to X86_R_xx (this makes building on Tru64 nicer). 20050422 Adding a check for duplicate MIPS TLB entries on tlbwr/tlbwi. 20050427 Adding screenshots to guestoses.html. Some minor fixes and testing for the next release. ============== RELEASE 0.3.2 ==============
